Answer:

2a + 3c + 4d

Step-by-step explanation:

This is the answer because:

1) Nothing further can be done to this equation since there are no like terms.

Therefore, the answer is 2a + 3c + 4d.

Hope this helps! :D

Step-by-step explanation:

It's given that A = 30° . Lets find the sin , cos & tan of A

⇒ [tex]\sin A=\sin30 = \frac{1}{2}[/tex]

⇒ [tex]\cos A = \cos 30 = \frac{\sqrt{3} }{2}[/tex]

⇒[tex]\tan A = \tan 30 = \frac{1}{\sqrt{3} }[/tex]

Lets solve the LHS (Left Hand Side) :-

[tex]2(\sin A \times \cos A) = 2(\frac{1}{2} \times \frac{\sqrt{3} }{2}) = \frac{\sqrt{3} }{2}[/tex]

Now lets solve the RHS (Right Hand Side) :-

[tex]\frac{2\tan A}{1+\tan ^{2}A } = \frac{2 \times \frac{1}{\sqrt{3} } }{1 + (\frac{1}{\sqrt{3} } )^{2} } = \frac{2}{\sqrt{3} } \div ( 1 + \frac{1}{3} ) = \frac{2}{\sqrt{3} }\div \frac{4}{3} = \frac{2}{\sqrt{3} } \times\frac{3}{4} =\frac{\sqrt{3} }{2}[/tex]

∴ LHS = RHS ( Proved )

Concept: Statistics

Step-by-step explanation:

gradient/slope = 3

y-intercept

2x - 3y = 4

3y = 2x - 4

y = 2/3x - 4/3

so y-intercept is double -4/3 so... -4/3x2 = -8/3

the equation of the line is

y = 3x - 8/3 or 9x - 3y = 8

Answer:

3y=2x-8

Step-by-step explanation:

when y intercept x=0

2(0)-3y=4

-3y=4

y=-4/3

when x intercept y=0

2x -3(0)=4

2x =4

x=2

point (2,-4/3)

gradient

-3y=-2x +4

y=2x/3-4/3

gradient=2/3

equation

y+4/3=2/3(x-2)

3y+4=2x-4

3y=2x-8

Answer:

You should mix 15 cups of yellow paint, because it takes 5 cups of yellow paint + one cup of blue paint to make the same green. Since there's 3 cups of blue paint, multiply that by 5, and you get 15.

Answer:

A. z = 7/2

Step-by-step explanation:

First, distribute the 5 into 2z and 7 to get 10z - 35 for the left side and the right side should be the same.  Add 2z on both sides to get to this equation 12z - 35 = 7.  Add 35 on both sides to get 12z = 42.  Divide 12 on both sides, since it is an improper whole number, the fraction would be left as 42/12.  However, both numbers can be divisible by 6 leaving your z value as 7/2.

Answer:

The answer is

[tex] \frac{7}{2} [/tex]

Step-by-step explanation:

1. Distribute

[tex]5(2z - 7) = - 2z + 7 \\ 10z - 35 = - 2z + 7[/tex]

2. Solve

[tex]10z - 35 = - 2z + 7 \\ \frac{+ 2z \: \: \: \: \: \: \: \: \: \: \: \: \: \: = + 2z \: \: \: \: \: \: \: }{12z - 35 = 7} \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: + 35 = + 35}{12z = 42 } \\ \\ \frac{12z}{12} = \frac{42}{12} \\ \\ z = 3.5 \: or \: \frac{7}{2} [/tex]

Answer:

  179/495

Step-by-step explanation:

When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.

Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.

Then the entire decimal is ...

  0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495

See the attachment below, co-interior angles lie at the same side of the transversal, or the line that crosses between the two parallel lines.

So if you are finding the co-interior angle of ∠AGH, then it is ∠CHG.

They are also supplementary angles and will add up to 180°.

Step-by-step explanation:

How do you calculate number of successes?

Example:

Define Success first. Success must be for a single trial. Success = "Rolling a 6 on a single die"

Define the probability of success (p): p = 1/6.

Find the probability of failure: q = 5/6.

Define the number of trials: n = 6.

Define the number of successes out of those trials: x = 2.

Binomial probability distribution for the given set of data is

[tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex].

"Binomial probability distribution is the representation of  a probability with only two outcomes success and failure under given number of trials."

Formula used

Binomial probability distribution is given by

[tex]\\n{C}_{x}p^{x}q^{n-x}[/tex]

n= number of experiments

x = 0, 1, 2, 3,.......

p = probability of success

q = probability of failure

According to the question,

Number of trials  'n' = 100

Probability of success 'p' = (20 / 100)

                                          = 0.20

Probability of failure 'q' = 1 - p

                                      = 1 - (20/100)

                                      =  (80 / 100)

Substitute the value in the formula we get

Required probability =  [tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex]

Example:

Tossing a coin 6 times getting exactly two heads.

Number of trials 'n' = 6

Number of heads 'x' =2

Only two possible outcomes head or tail

Probability of getting head 'p' = 1 / 2

Probability of not getting head 'q' = 1 /2

Required probability = [tex]\ 6C_{2[/tex] (1/2)²(1/2) ⁶⁻²

                                  =[tex]\ 6C_{2[/tex] (1/2)⁶

Hence, binomial probability distribution for the given set of data is

[tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex]

Answer:

The Width of each side of the bookmark in centimeters = 5cm

Step-by-step explanation:

A bookmark shaped like a rectangle has a total perimeter of38cm the length of the one of its sides is 14 what is the width of each side of the bookmark in centimeters

The formula for perimeter fo a rectangle =

P = 2L + 2W

Where L = Length

W = Width

Hence: From the above question:

38cm = 2 × 14 cm + 2 W

38cm = 28cm + 2W

2W = 38cm - 28cm

2W = 10cm

W = 10cm/2

W = 5cm

Hence, the Width of the rectangle(each side of the bookmark in centimeters) = 5cm

Answer:

Step-by-step explanation:

Using the trigonometric identities

tan a = [tex]\frac{sina}{cosa}[/tex], cot a = [tex]\frac{cosa}{sina}[/tex]

sec a = [tex]\frac{1}{cosa}[/tex], cosec a = [tex]\frac{1}{sina}[/tex]

Consider the left side

tana + cota

= [tex]\frac{sina}{cosa}[/tex] + [tex]\frac{cosa}{sina}[/tex]

= [tex]\frac{sin^2a+cos^2a}{cosasina}[/tex]

= [tex]\frac{1}{cosasina}[/tex]

= [tex]\frac{1}{cosa}[/tex] × [tex]\frac{1}{sina}[/tex]

= seca . coseca

= right side , thus proven
